Detailed explanation-1: -Net Primary Productivity (NPP), or the production of plant biomass, is equal to all of the carbon taken up by the vegetation through photosynthesis (called Gross Primary Production or GPP) minus the carbon that is lost to respiration.
Detailed explanation-2: -NPP = GPP-R GPP = gross primary productivity.
Detailed explanation-3: -* Respiration, R, is the amount of CO2 that is lost from an organism or system from metabolic activity. * Net Primary Production, NPP, is the net amount of primary production after the costs of plant respiration are included. Therefore, NPP = GPP-R .
Detailed explanation-4: -Divide output by input. Divide your production figure by the amount of energy you put into it. For example, 10, 000 units manufactured in a month using 400 kilowatt hours indicates that you divide 10, 000 by 400 to find a figure of 25. This means you made 25 units per kilowatt hour.
